Thanks for helping out. I finished the calibration last night, and I must say the results are very pleasing, with still a few points to clarify if possible, considering I'm a newbie at this and want to make sure I did things correctly.
First, the system and method I used:TV:
An old Samsung LN40A550 LCDHTPC:
AMD A6-5400k with Jriver TrialSpec:
Colormunki PhotoOutputs / Inputs:
Everything RGB 4:4:4 0-255Colorimeter:
Colormunki Create (clone of i1d2)
I set the TV to defaults (Movie Mode, no dynamic contrast, etc). Then I adjusted it using brightness / contrast. Also put in the mode closest to 6500k at 100 IRE (in my case, Warm1), and backlight somewhat close to 120cd/m2 (I have a reasonably dark room for watching, but not pitch black).
I warmed up the TV for 30 minutes with both calibration devices on it.
Then I ran dispcalgui, created a correction for the colorimeter based on the colormunki photo, and ran the calibration with high quality and Massive testchart for LUT profiles.
After it was done, I created a few 3dluts to test, based on the commands your provided:
1 - Regular, based on collink.exe -v -3m -qh -et -Et -Ib:2.2
2 - 188622, based on collink.exe -v -3m -qh -et -Et -IB:2.2
3 - 188624, based on collink.exe -v -3m -qh -et -Et -IB:2.4
After it was all done, I launched Jriver and applied each profile on several sources based on scenes I'm familiar with, and usually have either a lot of contrast (like a face on the sun with a shadow on the side), or dark scenes (inside a tavern), etc.
My initial impression is that BT 1886 with 2.2 gamma gave the most pleasing results. But it also gave a feeling sometimes of the blacks not being as deep as before.
As a final step, I re-ran the white and black clipping patterns (from AVSHD), and found something odd: With the profile applied, the flashing bars on the black pattern are now brighter, and in can see the 16 bar flashing again. Should I reduce the brightness and redo the calibration, or is this normal?
On the white clipping pattern, the bars are not "greyish" anymore, and I feel they got a bit of a yellow tone to them. To confirm, I removed the 3dlut and the bars immediately went back to grey. Can someone try this, and see if you get similar results?
As a last step, I used HCFR + the Spec to measure greyscale / primaries / secondaries and compare. I took measurements for everything running from Jriver (with AVSHD) for all the 3dluts mentioned above, as well as for the display without any 3dlut applied (uncallibrated).
From these results, looks like things got better. If someone has hcfr installed, can you have a look at my results and provide an opinion if these numbers look good, in particular the contrast curve?
Thanks so much for your help!
